"Conventional teaching files, and even dynamic interactive HTML schemes, are restricted to static views of a single radiograph, or single CT or MR slice, even though diagnosis of many processes requires multiple images," said Dr. Daniel Cornfeld, an assistant professor of radiology at Yale University School of Medicine.
Cornfeld's technique creates web-based scrollable cine from a stack of images. The system is portable and can be used to show cases at conferences, make web-based teaching files, or test residents (AJR 2008;(39):190).
"With this method, you can quickly and easily incorporate entire stacks of CT or MR images into online teaching files," Cornfeld said.
It is also easy to create PowerPoint hyperlinks to web pages containing image stacks, so users never have to leave PowerPoint during talks to display image stacks, he said.
"This makes the process completely portable," Cornfeld said. "I routinely use this technique to transport cases and to show cases at departmental and multidisciplinary conferences."
The Cornfeld technique can also be used to view cases remotely via the Internet.
